To all whom it may concern:

Be it known that I, FREDERICK M. MAY- BURY, of Milwaukee, in the county of Milwaukee, in the State of Wisconsin, have invented a new and useful Compound for. Cleaning Steam Boilers and Preventing Scale from Forming in the Same, which compound is fully described. in the following specification.

' This invention relates to that class of compounds used for cleaning the scale from steamboilers, and for preventing the scale from formingin the same; and it consists ina composition formed by mixing chicken-dun g W hair, soda, blood, salt, saltpeter,-alum, ammonia, and tar together.

To prepare the compound for making about forty-two gallons of the same, take'about ten gallons of chicken-dung, and put it in about thirty-five gallons of water and mix it thoroughly, and then strain it. Then put into the water, after the chicken-dung is strained out of it, about ninety pounds of leather, ten pounds of hair, and sixty pounds of soda, and boil the same in a vessel from twelve to fourteen hours, and then strain the same, and after straining add three gallons of blood, and

ther,

twenty five pounds of salt, and one, and a half pound of saltpeter, and boil again, about an hour, and then strain again, and when cold add three-fourths of a pound alum, one and one-half pound ammonia, and one-fourth of a gallon of tar, and the compound is completed.

If the Water used in the boiler is not very dirty or hard, the chicken-dung may be omitted, and for a larger or smaller quantity of the compound a larger or smaller quantity of the ingredients may be employed.

Use this compound as follows: For lake water, or any water of about that consistency, one quart for a ten-horse boiler, and in about that proportion for a larger or smaller boiler.

I claim- A compound composed of chicken-dung water, leather, hair, soda, blood, salt, saltpeter, alum, ammonia, and tar, in about the proportions and prepared substantially as described.
